Usinger's sausages in DC/NoVA/MD

I'm just back from a swell trip to Milwaukee, where I ate some of the tastiest fare the middle-West has to offer. Among the treats were various types of Usinger's sausages - brats (natch), Hungarian style sausage, Italian - so now I'm on the hunt for the company's products locally. I can order online from them but would like to avoid that and want to see if any place in the any carries their stuff. I thought perhaps one of the local Wegman's. I'm willing to travel a good distance for the stuff.

Thank you for the tip about Weis markets carrying Usinger's!!! It's almost Oktoberfest time and my trial-run Saurerkaut-smoked pork-and-sausage ("Bauernschmaus") was amazing -- except for the sausage. I have to get my hands on some real German sausage in a week or so.

As an ex-Wisconsinite, ordering online with them is actually a pretty good deal. They offer a much bigger selection of wurst than you could find of theirs locally. Plus they're very good about shipping -- generally reluctant to do so in the hot months, pack off fresh brats well, etc.
